Description

Technical Field

[0001] The utility model relates to the technical field of circuit breakers, in particular to a circuit breaker which is convenient for assembly and combination. Background Art

[0002] A circuit breaker is a switch device that can close, carry and disconnect current under normal circuit conditions and close, carry and disconnect current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The boundary between high and low voltage is relatively vague. Generally, those above 3kV are called high-voltage electrical appliances. Circuit breakers can be used to distribute electrical energy, start asynchronous motors infrequently, and protect power lines and motors. When they have serious overloads or short circuits and undervoltage faults, they can automatically cut off the circuit. Its function is equivalent to the combination of fuse switches and over- and under-temperature relays.

[0003] However, the existing circuit breakers are generally fixed by multiple groups of assembly type connections, and are generally fixed to the wall by bolts. When installing, the circuit breakers need to be fixed in the box with bolts one by one. This not only makes the circuit breaker inconvenient to install, but also when the circuit breaker is damaged and needs to be replaced, it is necessary to use a screwdriver to loosen the screws to remove the circuit breaker from the wall or the cabinet on the wall and replace it, which makes the maintenance of the circuit breaker more troublesome;

[0004] In order to solve the above problems, the present application proposes a circuit breaker that is convenient for assembly and combination. Utility Model Content

[0005] The utility model aims to provide a circuit breaker that is convenient to assemble and assemble, and is mainly used to solve the problem that the assembly and disassembly of the existing circuit breaker are relatively inconvenient, thus causing the circuit breaker to be troublesome to repair.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] A circuit breaker convenient for assembly and combination comprises a mounting seat and a plurality of circuit breaker bodies, wherein screws are passed through the four corners of the mounting seat, and the screws are threadedly connected to the mounting seat, a mounting block is fixedly connected to one side of the circuit breaker body, a plurality of mounting grooves matching the mounting block are provided on the mounting seat, and a limit assembly for fixing the circuit breaker body is provided on the top and the bottom of the mounting block.

[0008] The working principle and beneficial effects of the utility model:

[0009] 1. Working principle: When installing the circuit breaker, fix it on the wall or counter through the screws at the four corners of the mounting base, and then insert the mounting block on one side of the circuit breaker body to be installed into the mounting slot on the mounting base. The limit assembly can better fix the circuit breaker body. After the circuit breaker bodies to be installed are installed on the mounting base, the circuit breaker can be used normally.

[0010] 2. Beneficial effects: After the mounting base is fixed to the wall or counter by multiple screws, the mounting block on one side of the circuit breaker body to be installed is inserted into the mounting groove on the mounting base. The circuit breaker body can be better fixed by the limit assembly. When the circuit breaker is damaged during use, only the corresponding circuit breaker body can be disassembled and replaced without disassembling all the circuit breaker bodies or mounting bases. The advantage of this arrangement is that it makes the assembly and disassembly of the circuit breaker more convenient, thereby facilitating people to repair the circuit breaker.

[0011] Preferably, the limiting assembly includes sliding cavities on the top and bottom of the mounting block, wedge blocks are slidably connected to the inside of the sliding cavities, one side of the wedge block extends out of the sliding cavity, and the other side is fixedly connected to a telescopic rod, the other end of the telescopic rod is fixedly connected to the inner wall of the sliding cavity, the outer wall of the telescopic rod is sleeved with a spring, one end of the spring is fixedly connected to the wedge block, and the other end is fixedly connected to the inner wall of the sliding cavity, a limiting groove matching the wedge block is provided on the mounting seat, a push block is slidably connected to the inside of the limiting groove, one side of the push block is set to abut against the wedge block, and the other side extends out of the mounting seat, when installing the circuit breaker, after the mounting seat is fixedly installed on the wall or counter, the mounting block on one side of the circuit breaker body to be installed is then inserted The mounting block is inserted into the mounting groove on the mounting seat. During the process of inserting the mounting block into the mounting groove, the wedge block is squeezed and moves toward the inside of the sliding cavity, squeezing the telescopic rod and the spring and compressing the telescopic rod and the spring. When the mounting block is fully inserted into the mounting groove, the wedge block pops out under the action of the telescopic rod and the spring and engages with the limit groove on the mounting seat, thereby playing a good fixing effect on the circuit breaker body. When the circuit breaker body needs to be disassembled, the corresponding push blocks at the top and bottom of the mounting seat are pressed at the same time to push the wedge block to move into the sliding cavity. When the wedge block is completely out of the limit groove, the circuit breaker body can be removed from the mounting seat, thereby facilitating people to replace it.

[0012] Preferably, the screw is an embedded hexagonal setting, and the outermost end of the screw is not higher than one side of the mounting seat. After the screw is installed, the outermost end of the screw is not higher than one side of the mounting seat, so that it will not bulge out and cause wear. The screw is an embedded hexagonal setting, and the screw with an embedded hexagonal setting can rotate better during installation, reducing the possibility of slip angle.

[0013] Preferably, sliders are fixedly connected to both sides of the push block, and the inner wall of the limit groove is provided with slide grooves matching the sliders. When the push block slides inside the limit groove, the sliders arranged on both sides of the push block and the slide grooves provided on the inner wall of the limit groove can play a better limiting and guiding role for the push block. This not only makes the push block more stable when sliding inside the limit groove, but also effectively facilitates the push block to detach from the limit groove.

[0014] Preferably, there are two telescopic rods in the sliding cavity, and the telescopic rods are symmetrically arranged in the sliding cavity. By setting the number of telescopic rods in the sliding cavity to two, springs are sleeved on the outer walls of the two telescopic rods, so that the telescopic rods and the springs can exert a greater thrust on the wedge block, so that the wedge block and the limiting groove on the mounting seat can be better connected, thereby achieving a better fixing effect on the circuit breaker body.

[0015] Preferably, the corners at the opening of the mounting slot are chamfered. By setting the corners at the opening of the mounting slot as chamfers, it is easier to insert the mounting block into the mounting slot, thereby assembling the circuit breaker more conveniently.

[0016] Preferably, the corner where the push block extends out of one side of the mounting seat is rounded. By setting the corner where the push block extends out of one side of the mounting seat to be rounded, not only can people's hands be more comfortable when pressing the push block, but people's hand skin will not be scratched by the corner of the push block when pressing the push block.
